onyinyang: 2023-04-18
Last week(s):
- HACS
- DRL meeting
- AFK for 1 week
This week:
- Responding to pre-existing MR reviews and other
notifications/questions in gitlab
Probably next week and beyond:
- preparing for upcoming panel
- implement some preliminary user feedback mechanism to
identify bridge blocking based on Vecna's work
- improve metrics collection/think about how to show Lox is
working/valuable
- sketch out Lox blog post/usage notes for forum
- attempt hyper upgrade again
(long term things were discussed at the meeting!):
https://pad.riseup.net/p/tor-ac-community-azaleas-room-keep
- brainstorming grouping strategies for Lox buckets (of
bridges) and gathering context on how types of bridges are
distributed/use in practice
Question: What makes a bridge usable for a given user, and
how can we encode that to best ensure we're getting the most appropriate
resources to people?
1. Are there some obvious grouping strategies that we
can already consider?
e.g., by PT, by bandwidth (lower bandwidth bridges
sacrificed to open-invitation buckets?), by locale (to be matched with a
requesting user's geoip or something?)
2. Does it make sense to group 3 bridges/bucket, so
trusted users have access to 3 bridges (and untrusted users have access
to 1)? More? Less?

Last weeks:
- WIP: extended Pion dtls library to support mimicking of
client hellos. A github action generate fresh dtls handshakes of the
newest firefox and chromium versions. The bytes of the client hello are
replayed to mimick common dlts fingerprints.
Next weeks:
- Test and validate mimicked client hello with snowflake.
- PR to pion github, talk with sean.
